Nandina plant named ‘NanSid6’

ABSTRACT

A new cultivar of  Nandina domestica  named ‘NanSid6’ that is characterized by its foliage with new growth that is reddish purple in color and fall foliage that is red in color, its finely dissected foliage, and its compact, upright mounding habit with dense foliage.

Botanical classification: Nandina domestica.

Variety denomination: ‘NanSid6’.

CROSS REFERENCE TO A RELATED APPLICATION

This application is co-pending with a U.S. Plant Patent Application filed for a plant derived from the same breeding program that is entitled Nandina Plant Named ‘NanSid3’ (U.S. Plant patent application Ser. No. 15/530,724).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nandina domestica and will be referred to hereafter by its cultivar name, ‘NanSid6’. ‘NanSid6’ is a new cultivar of heavenly bamboo shrub grown for use as a landscape plant.

The new cultivar was discovered as a branch mutation by the Inventor in 2010 in Mission, British Columbia, Canada. The new cultivar arose as a naturally occurring branch mutation of Nandina domestica ‘Gulfstream’ (U.S. Plant Pat. No. 5,656) that was growing in a container at his nursery.

Asexual reproduction of the new cultivar was first accomplished under the direction of the inventor by tissue culture of meristematic tissue in spring of 2011 in Mission, British Columbia, Canada. Asexual propagation by tissue culture and stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘NanSid6’ as a unique cultivar of Nandina.

-   -   1. ‘NanSid6’ exhibits foliage with new growth that is reddish         purple in color and fall foliage that is red in color.     -   2. ‘NanSid6’ exhibits finely dissected foliage.     -   3. ‘NanSid6’ exhibits a compact, upright mounding habit with         dense foliage.

‘Gulfstream’, the parent plant of ‘NanSid6’, is similar to ‘NanSid6’ in growth rate and plant habit. ‘Gulfstream’ differs from ‘NanSid6’ in having foliage with new growth that is bronzy orange in color. ‘NanSid6’ can be most closely compared to the cultivar ‘NanSid3’ and ‘Sunset’ (U.S. Plant Pat. No. 24,748). ‘NanSid3’ is similar to ‘NanSid6’ in growth rate and plant habit. ‘NanSid3’ differs from ‘NanSid6’ in having foliage with new growth that is more red in color and in having less finely dissected foliage. ‘Sunset’ is similar to ‘NanSid6’ in having finely divided foliage that has new growth that is purple in color. ‘Sunset’ differs in having foliage that is more purple in color and in having a much more open and airy plant habit.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of two year-old plants of the new Nandina as grown outdoors in 1-gallon containers in St. Thomas, Ontario, Canada.

The photograph in FIG. 1 illustrates the overall plant habit and new foliage and mature foliage of ‘NanSid6’ in summer.

The photograph in FIG. 2 provides a view of the new foliage in spring of ‘NanSid6’.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of a 2 year-old plant of the new cultivar as grown outdoors in a 1-gallon container in St. Thomas, Ontario, Canada. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
